# VaultExecutor

Executes all pToken mint/redeem operations on behalf of Dual Investment flows, tracks protocol‑supplied amounts, and orchestrates swaps and settlement payouts.

## Responsibilities

* Redeem user pTokens, supply underlying back into markets under the vault, and mint cTokens to recipients.
* Withdraw underlying for settlement (clamped to available balance).
* Swap between underlyings via `PancakeSwapAdapter`, then mint target cTokens.
* Track per‑market protocol balances and per‑user redeemed underlyings.

## Key Functions

* `redeemAndSupplyToProtocol(user, cToken, cTokenAmount)` \[onlyAuthorized]
  * Redeems to underlying (delta), tracks `userUnderlyingBalances`, then supplies to market; updates `protocolSuppliedAmounts`.
* `withdrawUnderlyingFromProtocol(cToken, underlyingAmount)` \[onlyAuthorized]
  * Redeems required cTokens (based on exchangeRate) up to available balance.
* `swapUnderlying(tokenIn, tokenOut, amountIn, minOut)` \[onlyAuthorized]
* `swapAndMintTo(cTokenIn, cTokenOut, recipient, underlyingInAmount, minUnderlyingOut)` \[onlyAuthorized]
  * Swaps underlyings and mints cTokenOut to recipient; pays out raw underlying if amount too small to mint ≥1 cToken.
* `mintCTokensTo(cToken, recipient, underlyingAmount)` \[onlyAuthorized]
* `pullUnderlyingAndMintTo(cToken, fromUser, recipient, underlyingAmount)` \[onlyAuthorized]
* Admin: `setAuthorizedManager`, `setProtocolAccount`, `setSwapAdapter`, `emergencyWithdraw`.

## Notes

* Uses `forceApprove` for safe allowance setting prior to mint.
* Swap path tries V3 first, falls back to V2.
